How to Evaluate a Used Skydiving Rig Before You Buy

Buying your first skydiving rig is a massive milestone. It is also one of the most stressful purchases you will ever make. The market for used gear is flooded with listings that look pristine online but hide issues that could ruin your season—or worse, result in a reserve ride you could have avoided.

While a professional rigger inspection is mandatory (and legally required for reserves in the US every 180 days), you need to know how to spot the immediate red flags sellers don't always volunteer yourself. Wiring $4,000 to a stranger for a rig that turns out to have corroded grommets, a shrunk line set, or an expired AAD is a nightmare you can prevent.

This is the ultimate, step-by-step checklist for evaluating a used complete rig before you close the deal.

1. The Harness and Container: The Foundation of Safety

The container holds your life-saving devices, but the harness is what keeps you physically attached to them. A failure here is catastrophic.

Inspecting the Webbing and Stitching

Begin by laying the container flat on a clean packing mat. Run your hands along the main lift web (MLW), the leg straps, and the chest strap.

• Fraying: Look for fuzzy, broken nylon fibers. Light cosmetic fuzzing from Velcro is common, but any deep abrasion that cuts into the structural weave of the webbing is an immediate reject.
• Stitching: Examine the high-stress junctions, particularly the 3-ring attachment points and the harness junctions near the shoulders and hips. Look for broken threads, loose stitching, or evidence of amateur repairs. Skydiving rigs are sewn with specialized industrial machines and heavy duty nylon thread (usually Size E or F). Any hand-sewing is a major red flag.

Hardware and Grommets

Check all metal components, including the leg strap buckles, chest strap buckle, and the D-rings.

• Corrosion: Rust is an absolute dealbreaker. Marine environments (jumping near coasts) accelerate salt-water corrosion. Check the underside of buckles where sweat accumulates.
• Grommets: Look at every grommet on the container flaps. They should be perfectly round, tight against the fabric, and free of rough edges or cracks. Loose or distorted grommets can catch lines during deployment, causing a fatal malfunction.

The 3-Ring Release System

This is your primary safety mechanism. It must be in perfect condition.

• Check that the three rings are perfectly round, free of rust, and sitting completely flat against each other.
• Verify that the yellow Cable housing (Lolo) is clean and the Teflon-coated cables slide smoothly inside. A sticky or dirty release cable can prevent a clean cutaway when you need it most.

2. The Main Canopy: Where the Wear and Tear Lives

The main canopy takes the brunt of the abuse on every single jump. Fabrics degrade, lines shrink, and seams stretch.

Fabric Strength and Porosity

Most modern canopies are made from Zero-Porosity (ZP) fabric. ZP is designed to hold air, providing consistent openings and strong flares.

• Feel the fabric: Fresh ZP feels crisp, slippery, and slightly crinkly—like a new banknote. Old, worn-out ZP feels soft, thin, and resembles cotton cloth. If the fabric feels soft and heavy, the canopy is near the end of its lifespan.
• UV Damage: Sun exposure is the silent killer of nylon. Ask the seller how many sunset loads or packing sessions in direct sunlight the canopy has seen. Faded colors are a strong indicator of UV degradation.

Seams, Ribs, and Crossports

Open the canopy completely on a large table or clean floor.

• Inspect the top and bottom skins cell by cell. Look for small tears, pinholes (common from grass or sticks), and burn marks from sliding pack jobs.
• Look inside the cells. Inspect the internal ribs and crossports (the holes in the ribs that allow air to flow sideways). Ruptured crossports from hard openings are expensive to repair and ruin the canopy’s flight characteristics.

The Line Set and Trim

Canopy lines degrade from friction during slider movement and contact with dirt.

• Line Type: Identify the line material. Microline (Spectra) is incredibly durable but shrinks over time due to heat from the slider. Vectran and HMA do not shrink but degrade silently from UV exposure and wear, requiring replacement every 300–500 jumps. Dacron is thick, bulky, and mostly used for student or CRW rigs.
• Trim State: Over time, the front lines (A and B lines) stretch or the rear lines (C and D lines) shrink, putting the canopy "out of trim." This leads to sluggish openings, poor flares, and an increased tendency to search for a stall. Measure the line lengths against the manufacturer’s line trim chart if possible. If you are buying this canopy to step down in size, read our canopy downsizing guide before you commit to a smaller wing.

3. The Reserve Canopy: The Last Line of Defense

You only use your reserve when your day is already going badly. It must be absolutely flawless.

The Reserve Card and History

Every reserve canopy has an associated Reserve Packing Data Card. This card is the legal diary of the reserve.

• Verify that the serial number on the reserve fabric matches the number on the card exactly.
• Count the number of repacks and deployments. In the US, reserves must be inspected and repacked by an FAA-certified rigger every 180 days, regardless of use.
• Lifespan: Most manufacturers (like Performance Designs) set a limit on reserve canopy age or the number of deployments (typically 20-40 repacks or 25 jumps) before it must be sent back to the factory for testing. Never buy a reserve that has reached these limits.

Fabric and Lines

Inspect the reserve fabric for acid mesh damage. In the late 1990s and early 2000s, some reserves were manufactured with mesh that degraded the nylon fabric. A certified rigger must perform a tensile strength test to verify safety.

4. The Automatic Activation Device (AAD): The Silent Guardian

The AAD is a computerized system that automatically fires a cutter to slice your reserve closing loop if you are still at freefall speeds below a certain altitude (typically 780–840 feet for sport settings).

Lifespan and Service Intervals

AADs have strict lifespans and maintenance requirements that dictate their used value.

• Cypres 2: Older units have a strict 12.5-year lifespan and require 4-year and 8-year factory maintenance. Newer Cypres 2 units (manufactured after 2017) have a 15.5-year lifespan with voluntary maintenance cycles.
• Vigil 2 / Vigil Cuatro: These units have a 20-year lifespan and do not require mandatory factory service, but they must have their batteries replaced every 10 years or according to the firmware prompts.
• Doing the Math: Calculate the remaining life of the AAD. A used Cypres with only 1 year left on its clock is worth almost nothing, even if it functions perfectly today. Factor the cost of remaining life directly into your purchase price.

Key Takeaways

• Harness Integrity First: Any deep wear on the structural webbing or hand-sewn repairs means you should immediately walk away from the deal.
• Check the Reserve History: Ensure the serial number on the canopy matches the reserve card exactly, and verify the repack history is up to date.
• Calculate AAD Lifespan: AAD value depreciates linearly. Calculate exactly how many months of life remain before negotiating the price.
• Always Get a Rigger Check: Never buy used gear without an escrow agreement that allows a certified rigger of your choice to inspect the rig before funds are released.
